Two more people will plead guilty in the college admissions scandal, including a former USC soccer coach who has agreed to cooperate with the government’s widening investigation, federal authorities said Tuesday.

Laura Janke, an assistant soccer coach at USC from 2007 to 2014, will plead guilty to a racketeering charge and cooperate with prosecutors, the U.S. attorney’s office in Massachusetts said. Her cooperation could open a key line of inquiry for investigators, who are continuing to probe the admissions scam perpetrated by a Newport Beach consultant, William “Rick” Singer.

And a Bay Area couple who brokered a cooperation deal have been questioned about who at USC and UCLA knew of an athletic recruiting scam, people familiar with the talks have said. Singer has admitted to bribing university coaches and officials to slip the children of his clients into their schools as phony athletes.

Janke, 36, was for years deeply involved in the recruiting scheme, according to charging documents filed in federal court. She often served as Singer’s liaison with the coaches allegedly on his payroll and created athletic profiles, replete with lies and fake accolades, for the children of his clients, prosecutors allege.

Toby MacFarlane, a Del Mar title insurance executive, also will plead guilty to a fraud conspiracy charge, the U.S. attorney’s office said.

Prosecutors say MacFarlane, 56, paid $450,000 to ensure his two children were admitted to USC as recruited athletes. His daughter was recruited to the university as a soccer player in 2014 after submitting an athletic profile that said — among other falsehoods — she was a “U.S. Club Soccer All-American” for three years, according to a criminal complaint charging her father with fraud conspiracy. MacFarlane paid Singer $200,000 for the scam, prosecutors allege.

Singer, the scheme’s admitted mastermind, even wrote an essay for MacFarlane’s daughter that described her as intensely competitive on the soccer field, “the one who looks like a boy amongst girls with my hair tied up, arms sleeveless, and blood and bruises from head to toe.”

MacFarlane paid an additional $250,000 in 2017 to ensure his son, who is 5-foot-5, was recruited to USC as a basketball player, prosecutors allege. Despite his height and the fact he did not play on his high school’s varsity team until his senior year, MacFarlane’s son was admitted to USC as a basketball recruit in 2017, according to the FBI affidavit.

He attended the school briefly before withdrawing in 2018, prosecutors say.
